Jason Wrote:A required update is now available to the Left 4 Dead 2 Demo. Please run hldsupdatetool to receive it. The specific changes include:

Left 4 Dead 2:
- Fixed bug that caused dedicated servers to become unjoinable over time without a restart or heartbeat update
- Fixed exploit that allowed players to end a campaign and return to the lobby without a vote
- Public players are no longer matched to lobbies that are idle for a prolonged period of time. These lobbies become "Friends-only" lobbies
- LAN servers list will now show listen server single player games as not joinable and will show game type as "single player" too

Linux changes:
- srcds_run now supports two new options -nodefaultmap and -steamverify
-nodefaultmap will suppress this behavior in case you have specified a map in a config file
-steamverify will add -verify_all to the steam command line option when using -autoupdate
- srcds_run will now automatically add the +map option to the command line unless +map is specified
